Western Michigan University, 1992 The purpose of this study was to compare the effectiveness of using one instructional method versus another in teaching multiview orthographic projection to college students possessing varied spa­ tial visualization abilities. Two instructional methods were used: (1) the traditional hinged glass box method and (2) an unconven­ tional method in which an object is placed in the middle of a bowl/ hemispheric shape where the front view of the object is seen by looking directly into the bowl. Other views are developed by slid­ ing the object along the surface of the bowl until they are at right angle to the viewer's line of sight. The independent variable manipulated was the instructional method and the dependent variable was the spatial visualization development of students as demon­ strated through their a b ility to mentally solve complex multiview orthographic projection problems. The subjects were mostly freshmen and sophomores majoring in engineering technology enrolled in two intact basic engineering graphics classes at Ferris State University, Big Rapids, Michigan. The sample size was 92. The Differential Aptitude Test, Space Rela­ tions: Form T (DAT-SR-T, Bennett, Seashore, & Wesman, 1972) was Reproduced with permission of the copyright owner.

Scores attained on the DAT-SR-T were used to divide the subjects into three groups and four visualization aptitude levels. Subjects were also given a 12-item pretest for multiview orthographic projection knowledge, taken from the Western Michigan University (Kalamazoo) Career Guidance Inventory Part 4 (Nowak, Walter, Vander Ark, & Henry, 1980). Group 1 received 2 hours of instruction using glass box imagery, Group 2 received 2 hours of bowl imagery, and Group 3 re­ ceived no formal orthographic instruction. Hypotheses were formu­ lated and tested for significant differences between treatment and control groups for each aptitude level. The 12-item orthographic test was given to all subjects to record spatial visualization abil­ ity gains. The data collected were analyzed using the Statistical Package of Social Sciences (SPSS, Inc., 1990) software, Release 4.1. No significant difference in spatial visualization gain scores was found between treatment groups or aptitude levels at the .05 level. Reproduced with permission of the copyright owner.

  • On El Lissitzky's Representations of Space
    Online Journal of Art and Design volume 3, issue 3, 2015 Scissors versus T-square: on El Lissitzky’s Representations of Space Acalya Allmer Dokuz Eylül University, Turkey [email protected] ABSTRACT The first exhibition of Russian art since the Revolution was held in Berlin at the Van Diemen Gallery in the spring of 1922. In Camilla Gray’s terms it was ‘the most important and the only comprehensive exhibition of Russian abstract art to be seen in the West’ (Gray, 1962:315). The exhibition was organized and arranged by Russian architect El Lissitzky who acted as a link between the Russian avant-garde and that of the west. He played a seminal role especially in Germany, where he had lived before the war and where he was a constant visitor between 1922 and 1928. The diversity of El Lissitzky’s talents in many fields of art including graphic design, painting, and photography made him known as ‘travelling salesman for the avant-garde.’ However, what makes the theoretical and visual works of Lissitzky discontinuous and divergent is that they include apparently contradictory domains. Through his short life by shifting different modes of representations - perspective, axonometry, photomontage - Lissitzky sometimes presented us a number of problems in his irrational way of using the techniques. This article concentrates on his contradictory arguments on representation of space especially between 1920 and 1924, by re-reading his theoretical texts published in the avant-garde magazines of the period and looking through his well-preserved visual works. Keywords: El Lissitzky, representation, space, axonometry, photography, avant-garde 1.

  • The Agency of Mapping: Speculation, Critique and Invention
    IO The Agency of Mapping: Speculation, Critique and Invention JAMES CORNER Mapping is a fantastic cultural project, creating and building the world as much as measuring and describing it. Long affiliated with the planning and design of cities, landscapes and buildings, mapping is particularly instrumental in the construing and constructing of lived space. In this active sense, the function of mapping is less to mirror reality than to engender the re-shaping of the worlds in which people live. While there are countless examples of authoritarian, simplistic, erroneous and coer­ cive acts of mapping, with reductive effects upon both individuals and environments, I focus in this essay upon more optimistic revisions of mapping practices. 1 These revisions situate mapping as a collective enabling enterprise, a project that both reveals and realizes hidden poten­ tial. Hence, in describing the 'agency' of mapping, I do not mean to invoke agendas of imperialist technocracy and control but rather to sug­ gest ways in which mapping acts may emancipate potentials, enrich expe­ riences aJd diversify worlds. We have been adequately cautioned about mapping as a means of projecting power-knowledge, but what about mapping as a productive and liberating instrument, a world-enriching agent, especially in the design and planning arts? As a creative practice, mapping precipitates its most productive effects through a finding that is also a founding; its agency lies in neither repro­ duction nor imposition but rather in uncovering realities previously unseen or unimagined, even across seemingly exhausted grounds. Thus, mapping unfolds potential; it re-makes territory over and over again, each time with new and diverse consequences.

    189_09 aju 03 Bryon 8/1/10 07:25 Página 31 Measuring the qualities of Choisy’s oblique and axonometric projections Hilary Bryon Auguste Choisy is renowned for his «axonometric» representations, particularly those illustrating his Histoire de l’architecture (1899). Yet, «axonometric» is a misnomer if uniformly applied to describe Choisy’s pictorial parallel projections. The nomenclature of parallel projection is often ambiguous and confusing. Yet, the actual history of parallel projection reveals a drawing system delineated by oblique and axonometric projections which relate to inherent spatial differences. By clarifying the intrinsic demarcations between these two forms of parallel pro- jection, one can discern that Choisy not only used the two spatial classes of pictor- ial parallel projection, the oblique and the orthographic axonometric, but in fact manipulated their inherent differences to communicate his theory of architecture. Parallel projection is a form of pictorial representation in which the projectors are parallel. Unlike perspective projection, in which the projectors meet at a fixed point in space, parallel projectors are said to meet at infinity. Oblique and axonometric projections are differentiated by the directions of their parallel pro- jectors. Oblique projection is delineated by projectors oblique to the plane of pro- jection, whereas the orthographic axonometric projection is defined by projectors perpendicular to the plane of projection. Axonometric projection is differentiated relative to its angles of rotation to the picture plane. When all three axes are ro- tated so that each is equally inclined to the plane of projection, the axonometric projection is isometric; all three axes are foreshortened and scaled equally.

    O'SHAUNGHNESSY | The 1866 Vercoe and Harding map and the axonometric: the object of subjective representation AHA: Architectural History Aotearoa (2010) vol 7:58-65 The 1866 Vercoe and Harding map and the axonometric: the object of subjective representation Katherine O'Shaunghnessy ABSTRACT: The 1866 Vercoe and Harding map of Auckland provides a visual description of colonial development during the 1860s. This map is a static representation of the past and the backdrop to an exploration of the site via architectural drawing. This paper outlines the process of excavating a site through axonometric drawing looking specifically at an area within Freemans Bay. It explains how the two dimensional Vercoe and Harding map has been extruded into a three dimensional representation of the site. The idea of the map as a subjective representation of the past will be explored alongside the use of what might be considered an objective drawing type to create a subjective visualization of the site. The paper will investigate the process of creating this axonometric and the way in which this drawing relies on both historical fact and historical assumption. It will address how this process produces an understanding of the site, namely, the ability to translate each building based on the simple outline of its plan. This paper is part of a wider investigation into the documentation of heritage sites and the use of drawing to create an understanding of place. Thus, this drawing alone does not create this awareness of place, but rather, informs a new understanding of the 1866 map and a representation of what Freemans Bay might have been during the 1860s.

  • Axonometry and New Design of Bauhaus
    Journal for Geometry and Graphics Volume 11 (2007), No. 1, 73{82. Axonometry and New Design of Bauhaus Michio Kato General System Studies, Graduate School of International and Interdisciplinary Studies The University of Tokyo 3-8-1, Komaba, Meguro City, 153-8902, Tokyo, Japan email: [email protected] Abstract. In this paper we analyze and clarify the relationship between the use of axonometry and the new design tendency of Bauhaus. First we analyze the three characteristics of axonometry: 1) an image of appearance and an image of objects themselves | their ambivalence, 2) a tendency from a limited world with a human center to one already ¯xed in¯nite world of objects, 3) engineer's language. Then we analyze the new design of Bauhaus, we point out the following three characteristics corresponding to axonometry: 1) from an image of appearance to an image of objects themselves, 2) co-existence of a limited world with a human center and one already ¯xed in¯nite world of objects, 3) a tendency toward seeing a building as a `machine'. In short, the main characteristic of axonometry as a visualization tool is the ob- jecti¯cation of vision. This tendency is less explicit in isometric projection, which is one of orthogonal projections having characteristics similar to perspective, than in military projection which does not simulate individual's view, as this paper clari¯es. Bauhaus in the early years maintained an individual's subjective, indi- vidual vision by using isometric projection. On the contrary, other contemporary modernists such as De Stijl used only military projection.
